Windshield wipers won't turn off in 02 buick lesabre cust? Even in off position on 2002 Buick LeSabre

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The wipers are off only when ignition is off. Two speeds, regular and fast but they won't shut off when driving. If it rains everyday I'm OK but the sun is shining. Any help would be appreciated.

The switch in your car is more than likely broken. You will have to get a new switch and replace it.
GM has a lot of problems with the wiper control board. While the switch is off and wipers are running tap on the wiper control board with the handle of a screwdriver. If the wipers stop you need a control board.
Where is the windshield wiper control board located?
